A vise comprising a main bar; a guide holder pivotably mounted on the main bar and having a guide channel; a slide bar coextensive with the main bar and extending through the guide channel, and a holding pin secured to the guide holder and urged into engagement with the inner side face of the slide bar by a spring. A pair of jaws opposed to each other extend from the front ends of the bars respectively at right angles to the bars. When the guide holder is depressed against the action of the spring, the holding pin is disengaged from the inner side face of the slide bar, rendering the slide bar freely slidable forward or rearward.
